No. 124,961 Claims priority, application Great Britain Feb. 4, 1961 14 (Claims. (Cl. 1216.4)

This invention relates to machines for uniting loose prefinished outsoles and loose Louis heels, for example, preparatory to attaching the resultant outsole-heel units to shoes, and is directed to an improved machine of the general type disclosed in an application for United States Letters Patent Serial No. 87,933, filed February 8, 1961 in the names of Harold E. Elliott et al.

The outsole of the above-mentioned outsole-heel unit, which commonly includes a high style Louis heel, has a flap portion formed thereon, said flap portion being cemented to the breast of the loose heel so that in the finished shoe the outsole presents a continuous surface extending from the toe end of the shoe along the forepart and shank of the shoe bottom and down the breast face of the heel to the top lift receiving end of said heel. It will be appreciated that heels vary in style, some having broad low breasts and others having high slender breasts. In joining the outsole and the heel it is difiicult to determine the correct relation in which the outsole shall be joined to the heel so as to provide the outsole-heel unit of the proper all over length to fit the bottom of the shoe to which it is to be attached, and so that the outsole of the heel shall be properly alined laterally to fit the shoe bottom.

With shoes having extremely high style heels the problem of providing an outsole-heel unit which will fit the bottom of the shoe is especially complex because of the fact that the outsole is in a fiat condition when it is joined to the heel but is subsequently bent and twisted to assume the contour of the bottom of the shoe and accordingly the position of the toe end of the outsole is subsequently changed with relation to the heel in assuming the shape of the shoe bottom.

An object of the present invention is to provide a machine for quickly and effectively providing with a minimum amount of effort on the part of the operator outsoleheel units which will accurately fit the bottoms of shoes of different sizes and/ or styles. With the above object and considerations in view the illustrative machine is provided with means for supporting and positioning an outsole which has a breast flap portion, means for supporting and positioning a heel, a resilient block, means comprising mechanism for effecting relative movement between the first and second-named means on the one hand and the block on the other hand to cause the breast of the heel and the breast flap portion of the outsole to be forced together in correct nestled relation, and in accordance with a feature of the invention, power means operative in response to said relative movement for causing the breast of the heel and the breast flap portion of the outsole to be forced together under heavy secondary pressure.

In the illustrative machine the means for supporting and positioning the outsole and the heel comprises a template mounted upon a carrier or table which in accordance with another feature of the invention is manually tilted together with the template about an axis with relation to the resilient block whereby to cause the breast of the heel and the breast flap portion of the outsole to be forced together initially. The above'mentioned power operated means in accordance with a further feature of the invention comprises resilient pads or plungers which are opera- 3,5h,l49 Patented Oct. 2, 1952 IQQ tive respectively against the lower portion of the rear face of the heel and against the rear portion of the rim of the attaching face of the heel to force with heavy secondary pressure the breast of the heel against the breast flap portion of the outsole supported by the resilient block.

In the illustrative machine hereinafter described provision is made for the carrier or table to support a pair of templates arranged side-by-side, the carrier in accord ance with another feature of the invention being adapted to move the templates successively between a flap applying station arranged opposite the resilient block and one of two loading and unloading stations which are arnanged respectively at opposite sides of the operating station, the construction and arrangement being such that while work positioned in one template is being operated upon at the flap applying station, work may be placed in the work receiving cavity of the template at one of the loading and unloading stations.

The cavities of the templates are shaped fittingly to receive the outsole and the heel in such a relation that there is provided an outsole-heel unit of a predetermined size and shape to fit on the bottom of a particular shoe to be operated upon, the templates being readily slipped into guideways of the carrier for positioning against a stop face of the carrier and being readily removed and replaced by another template of a different size and/or style to accommodate the work on hand.

The present invention consists in the above features and in novel features hereinafter described, reference being had to the accompanying drawings which illustrate one embodiment of the invention selected for purposes of illustration, said invention being fully disclosed in the following description and claims.

In the accompanying drawings,

FIG. 1 is a right side view of the illustrative machine in its rest position, an outsole and a heel being positioned on a table of the machine;

FIG. 2 is a view similar to a portion of FIG. 1 showing the machine in the process of applying a breast flap portion of the outsole to the breast of the heel;

FIG. 3 is a section on the line II*I--III of FIG. 2;

PEG. 4 is an enlarged perspective view showing details of a heel engaging pad of the illustrative machine;

FIG. 5 is a view of the machine in the direction of an arrow V shown on FIG. 1; and

FIG. 6 shows in perspective the outsole and heel which have been united by the use of the above machine to form an outsole-heel unit which is subsequently attached to the shoe.

The illustrative machine is described with reference to the attachment, by the use of cement for example, of a heel H to a heel breast flap portion F of an outsole S to provide an outsole heel-unit 3 which is subsequently secured to the bottom of a shoe (not shown). Cement is commonly applied to the breast of the heel H and/ or to the flesh side of the breast flap portion F of the outsole S just prior to the above outsole and heel assembling operation.

The illustrative machine is fixed to a bench 2 at which an operator may be seated and comprises a prefabricated sheet steel main frame 4 adapted to support the various operative instrumentalities of the machine. Journaled in bearing bores formed in opposite side members of the frame 4 is a 3-arm lever or actuator 6, forwardly and rearwardly extending arms of which provide projections 10, 12 respectively against which rests a carrier or table 8. As will be hereinafter explained, the carrier 8 comprises right and left units 9 which are arranged side-byside and are adapted to receive templates 11 each having a cavity 13 for fittingly receiving an outsole S and its associated heel H. The terms forwardly and rearwardly used herein refer respectively to directions of movement toward and away from an operator seated in front of the machine. The carrier supporting projection extends upwardly from the forwardly extending arm of the actuator 6 and is formed integral therewith while the carrier supporting projection 12 extends upwardly from the rearwardly extending arm of the actuator 6 and has the form of an adjustable spring plunger as will be hereinafter explained.

Oppositely disposed and downwardly extending side flanges 14 of the carrier 8 are fixed to opposite ends of a shaft 16 extending laterally of the machine through a bore 15 in a hub or sleeve portion 18 of the lever or actuator 6. The hub portion 18 of the actuator 6 is journaled in and extends laterally beyond the opposite side members of the frame 4 and provides adequate bearing for the shaft 16. The actuator 6 and the carrier 3 are thus mounted on the main frame t for rotation about a common axis 17 of the shaft 16 and of the hub portion 18 of the actuator.

The shaft 16 is mounted for sliding movement laterally of the machine in the hub portion 18 of the actuator 6 between limits determined by the engagement of the flanges 14 of the carrier 8 with end faces of said hub portion, in order to move work, which comprises the outsole S and heel H supported by the carrier or table 8, between an operating station 19 where pressure is applied against the work, and simultaneously therewith to move an outsole and a heel which are mounted on the carrier and have already been secured together at the operating station, to a loading and unloading station 21 which is arranged at one side or the other of the operating station and in which the work may be placed in or removed from the machine.

As will be hereinafter explained, the carrier or table 8 is mounted on and is secured to the shaft 16 and has its position about the axis 17 controlled by the projections 10 and 12 of the actuator 6. The actuator 6 is normally urged clockwise (FIGS. 1 and 2) by a spring so that a depending arm 22 of the actuator engages one of a plurality of faces 23 of a stop 24, a shank of which is threaded into and is initially secured by a nut 25 to the main frame 4. The faces 23 of the illustrative stop 24 are spaced different distances from the axis of the shank of said stop and accordingly the stop may be moved to any one of six alternative positions, the carrier or table 8 during this time being supported by the projection 10, 12 of the actuator 6 so that it occupies the position shown in FIG. 1.

With the work carrier or table 8 thus supported the operator slides the carrier 8 laterally of the machine, that is, lengthwise of the axis 17, on the hub portion 18 of the actuator 6 by the use of knobs 26, which are screwed into the carrier and its associated shaft 16, whereby to move one of the templates 11 mounted on the carrier to the operating station 19 while the other template is moved to the loading and unloading station 21 at one side or the other of the operating station. Since the shaft 16 and the knobs 26 threaded into the shaft are secured rigidly to the table or carrier 8 they may be considered as part of the carrier.

In order that the carrier 8 may slide freely over the projections 10, 12 with a minimum amount of play be tween the carrier and the actuator 6 the aforesaid spring plunger 12 may be initially adjusted lengthwise thereof on the actuator as will be hereinafter explained. The spring plunger 12 is slidable in a bore of the boss of the actuator 6, a lower end of a stem portion 28 of the plunger having threaded onto it a stop nut 30. A compression spring 32, contained in the boss and surrounding the stem portion 28 of the plunger 12, urges said plunger toward the carrier 8 to a limit determined by the stop nut 30 with an under face of the boss. By appropriate adjustment of the nut 30 the carrier supporting face of the spring plunger 12 may be positioned relatively to the supporting face of the projection 16 so that the carrier 8 is free for sliding movement laterally of the machine. It will be realized that if the spring plunger 12 is allowed to exert too heavy pressure against the carrier 8 considerable friction will be encountered in moving the carrier lengthwise of the axis 17, whereas if the plunger 12 does not exert a fair amount of pressure against the carrier, said carrier may tilt to some extent between the projection 10 and the plunger 12 and this unsteadiness of the carrier may hinder the operator in the loading of the work thereon.

The flanges 14 of the table 8 may be referred to as abutments which are adapted to engage opposite ends of the sleeve 18 to position one or the other of the templates 11 at the flap applying station 19 while the other template is at the loading and unloading station 21. The actuator 6, which is secured to the sleeve 18, may be described as having rigid and yieldable abutment portions 10, 12 respectively adapted to engage different lengthwise portions of the table 8 arranged at opposite sides of the axis 17 of the sleeve 13.

The illustrative machine, which as above explained, is constructed and arranged to secure by the use of adhesive the heel breast flap portion F of the loose outsole S to the breast or breast face of the loose heel 1-1, is provided with the above-mentioned templates 11 for positioning the outsoles and their associated heels preparatory to attaching said outsoles and heels together. The cavity or opening 13 of each of the templates 11 is shaped fittin'gly to receive the fore part and the shank of each outsole and the rim of the attaching face of the heel which is to be attached to the outsole, said rim defining the upper end of the heel.

Each template 11 is conveniently made from two similar pieces of pattern or fiber board adhesively secured together, the work receiving opening or cavity 13 extending through one of said pieces only. The templates 11 are located on the carrier 8 by means of spaced opposing guideways 38 formed in the units 9 of the carrier, the templates being inserted in the guideways from the rear end of the carrier and being positioned therein by engagement with a face 37 of an upturned front edge 39 of the carrier. By providing the carrier 8 with two units 9 for receiving the templates 11, it will be apparent that one of the templates will normally occupy the operating station 19 of the machine while the other template in the carrier is arranged at one of the loading and unloading stations 21 at one side or the other of the operating station. Accordingly while work positioned by the template 11 at the operating station 19 of the machine is being operated upon, work may be placed in the template at the left or right of said operating station as viewed from the operators position at the front of the machine. Having performed the attaching operation on said work at the operating station 19 of the machine and placed work to be operated upon in the template 11 at the left-hand side thereof for example, the operator may move the carrier 8 laterally of the machine as hereinbefore described to carry the work to be operated upon to the operating station, the work previously operated upon being moved to the right side of the operating station, as indicated in dashlines (FIG. 5) for removal from the machine, said work being replaced by further work which is to be operated upon.

in positioning the outsole S and the heel H in the template 11 the operator places the heel H in inverted position in the heel end of the cavity 13 formed in the template and positions the forepart and shank of the outsole, tread face up, in outsole receiving portions of the cavity, the flap F lying against the breast of the heel. A recess 49 is provided in the heel end of each of the templates 11 and extends forwardly into the heel end of the Work receiving cavity 13 for a purpose hereinafter explained. Accordingly, a portion of the back edge or rim of the attaching face of the heel positioned in the cavity 13 bridges said recess 46. The recess 4% lies over a similar recess 443a provided at the rear end of the carrier 8.

Having positioned the outsole S and the heel H relatively to each other the operator moves the carrier 8 laterally of the machine by the use of the knobs 26 to trans fer the work to the operating station 19 in which the heel and the flap lying thereagainst occupy a position between a resilient presser member or block 41 and a clamp arrangement comprising a heel seat clamp generally referred to in the drawings by reference numeral 42 and a heel stem clamp generally referred to in the drawings by reference numeral dd. The forwardly extending arm of the lever or actuator 6 is connected by means of a chain 46 to a treadle 48 which the operator depresses to swing the work at the operating station into engagement with the resilient block 41. Depression of the treadle 4S swings the actuator 6 counterclockwise as viewed in FIGS. 1 and 2, the spring plunger or projection 12 of the actuator urging the carrier f) to swing in the same direction. The outsole S and the heel H thus assume positions in which the flap F of the outsole assumes the general curvature of the breast of the heel which is forced into nestled relation against the flap supported by the block.

The resilient block 41 is shaped to conform to the breast face of the heel and to the adjacent shank portion of the outsole being operated upon. The block 41 is supported in a holder 54? by means of two pins 52 which have bent handle portions and may be quickly withdrawn to replace the block with another block of a different shape.

The holder is carried by an arm 54 depending from an overhanging forwardly extending portion 56 of the main frame 4. A curved face 53 of the holder 50 fits against a complementary face of the arm 54, a screw 57 threaded into the holder 50 projecting through an arcuate slot 51 in the arm 54 and receiving a knurled nut 58 which seats on a shoulder formed by an enlarged portion of the slot 53. and serves to hold the screw 57 and accordingly the block 41 in its initially adjusted position on the arm 54-. By releasing the nut 58 the holder Stl may be angularly adjusted relatively to the arm 54 to accommodate the work on hand. The resilient block 41 may also be adjusted directions substantially heightwise of a heel H presented to the machine. The upper end of the arm 54 is threaded into a knurled hand nut 61} mounted for rotation in the portion 56 of the main frame 4 so that by rotation of the hand nut 61 the arm 54 may be raised or lowered in the machine to adjust the heightwise disposition of the presser member 41.

As explained above, initial depression of the treadle 48 causes the heel H and the breast flap or flap portion F of the outsole S to approach the resilient block 41, said flap being sandwiched with initial or primary pressure between the heel and the block in nestled relation. The carrier 3 is so constructed and arranged that the template 11 which positions the outsole S and the heel H relatively to each other is free to move a limited amount for the work to take up the correct position relatively to the block 41. For instance, the template 11 may move rearwardly on the carrier 8 for the work to accommodate itself against the resilient block 41 as shown in FIG. 5 where the face 37 of the carrier 8 at the operating station 19 of the machine is shown spaced slightly from the forward end of the associated template 11. Furthermore, the templates ll are arranged to fit loosely between their associated guideways 38 so that they may move laterally or twist within limits in order for the work to assume a natural position relatively to the resilient block 41. It will of course be realized that the outsole S and the heel H maintain their correct positions relatively to each other in the template it.

In order to reduce to a minimum the clearance between work moved into the operating station 19 of the machine and the resilient block 41 and accordingly the distance necessary to swing the work into contact with the block,

t5 the stop 24 is provided with the aforesaid faces 23 and is eccentrically mounted for rotation on the frame 4 to present the best adapted face to the arm 22 of the actuator 6.

Having carried the work into mating engagement with the resilient block 41 by initial depression of the treadle 48, continued depression of the treadle 48 further to rotate the actuator 6 counterclockwise as viewed in FIGS. 1 and 2 causes the spring plunger 12 to yield against its associated spring 32 and a screw 64 threaded into the actuator 6 to depress a plunger 66 of a valve 68 with the result that the valve which is connected to a compression air supply is opened and thus renders high pressure air available to operate the heel seat and heel stem clamps 42, 44. The screw 64- may be adjusted in the arm 22 so as to actuate the plunger 66 and accordingly to open the valve 68 only after the work has been correctly engaged against the resilient block 41.

Each of the clamps 42, 44 comprises a conventional air operated piston and a cylinder device having piston rods 70, 72 respectively. The piston and cylinder device of the heel clamp 42 is pivotally mounted on a pin 73 at the rear end of the frame 4-, a forward end of said device resting on a screw 74 which is threaded into a boss of the frame 4 and may be adjusted heightwise to control the direction of movement of a clamp abutment or pad 76 mounted on a holder 77 secured to the for ward end of the piston rod 70. The piston rod 70, the holder 77 and the pad 76 may be collectively referred to as a plunger.

The piston and cylinder device of the heel stem clamp 4-4 is fixed at a convenient angle to the frame 4 for a clamp abutment or pad 78 mounted on the forward end of the piston rod 72 to be able to engage work to be operated upon. The abutments or pads 7 6, 78 are noranally held in retracted inactive positions shown in FIG. 2 by springs 79, 81 respectively. The piston rod 72 and the pad 78 may be collectively referred to as a plunger. The opening of the valve 68 as hereinbefore described admits air under pressure by way of pipe lines 89 to the piston and cylinder devices 42, 44 to move the piston rods 70, 72 to the left as viewed in FIGS. 1 and 2 to carry the clamp abutments or pads 76, 78 in directions to engage portions of the back of the heel H at the operating station 19 whereby to press with secondary pressure the work assembly against the resilient block 41, the heel moving independently of the template.

As hereinbefore described, the direction of movement of the pad 76 may be initially adjusted by means of the screw 74, the construction of the illustrative machine being such that the abutment 76 is adapted to engage and apply pressure on the extreme back curve edge or rim of the attaching face of the heel in a direction so as to embed the curvature of the heel breast and the outsole flap portion directly against the complementary curvature of the resilient block 41. To avoid damage to the back of the heel H being operated upon, each abutment or pad 76, 78 is preferably made of resilient material, the abutment 76 having a notch 32 cut in its front face to bite over the heel seat edge (FIG. 2) and positively to control the direction in which pressure is applied to the heel. The notch is approximately V-shaped in cross section and extends laterally of the machine in the abutment or pad 76 as shown in FIG. 5. To accommodate the arcuate curvature of the heel the base of the V-shaped notch 32 is arcuate in shape lengthwise of the notch. In order automatically to cater to various heightwise variations in the positions of the heel seat back curves of the heels, the heel seat clamp 42 may be initially set by means of the screw 74 so that at least a portion of the top face of the notch 82 engages the heel seat edge when engaged by the pad 76, continued advancernent of this pad toward the heel causing the clamp 42 to swing upwardly a small amount on its mounting pin 73 in the frame 4 for the notch 82 to bite correctly on the heel seat edge. The pad '76 may be defined as mounted for displacement laterally of its path of movement to accommodate itself to the position and path of travel of the rear upper end portion of the heel as the heel is moved toward the resilient block 41. A rearwardly extending and comparatively wide guide member 83 is fixed at its forward end to a forward portion of the piston rod 7t? and accordingly to the pad holder 77, the rearwardly extending portion of said member lying against an upper face of the associated heel seat clamp 42 for sliding movement with the piston rod 7th but preventing any tendency for the piston rod and accordingly the pad 76 to rotate about the axis of said rod.

With the treadle 48 held depressed to hold open the valve 68 the work is held clamped between the block 41 and the clamps 42, 44 as shown in FIG. 2. The pad 76 approaches the rim of the attaching face of the heel to engage it in operative position through the recesses 40, 40a in the template Ill and the carrier 8 respectively. It will be noted that the recesses 4h, 49a extend far enough beneath the work for the rim of the heel seat of the heel to bridge them so as to present an unobstructed edge on which the abutment 76 may bite.

As aforesaid the clamp 44 is arranged to force the lower stem or shank portion of the heel against the block 41. Should a comparatively low heel be operated upon it may be unnecessary to utilize the clamp 44 which may be rendered inactive in such a case by cutting off the supply of air under pressure to its associated piston and cylinder device by the use of a valve 84.

While the treadle 46 is held depressed for a satisfactory bond to take place between the breast flap portion of the outsole and the heel, the operator may position work at one of the loading and unloading stations 21 of the machine. Upon release of the treadle 4-6 the valve 68 is allowed to close and cut ofl. the air supply to the clamps 42, 44 which are then returned by the springs 79, 81 to their retracted or inactive positions. Release of the treadle 46 and retraction of the clamps 42, 44- allows the spring 2th to return the actuator 6 and accordingly the carrier 8 to their normal positions with the arm 22 of the lever in engagement with the active face 23 of the stop 24.

With the carrier 8 in its normal position and the work supported thereon at the operating station 19 and spaced from the resilient block 41 the carrier is free so that the operator may move the work laterally away from the operating station 19 to one of the loading and unloading stations 21 preparatory to removing the work from the machine, work which has just been positioned in the carrier at the other loading and unloading station 21 being moved to the operating station 1%.

In a machine for assembling a loose outsole and a loose Louis heel, a fixed frame, a resilient block adjustably secured to the frame, a table mounted on the frame for tilting movement about an axis, a template which is adapted to support and to position a heel and an outsole with a flap portion of said outsole overlying a breast of the heel and which is mounted upon the table with a slight degree of play lengthwise and widthwise of the template, means for moving the table between a retracted position in which the template is substantially spaced from the resilient block and a projected position in which the heel in the template is forced with initial pressure against the flap portion of the outsole in said template and said flap portion is forced against the block, and power means for moving the heel independently of the template for causing the breast of the heel and the flap portion of the outsole to be forced together under heavy secondary pressure.

12. In a machine for assembling a loose outsole and a loose Louis heel, a fixed frame, a resilient block adjustably secured to the frame, a table mounted on the frame for tilting movement about an axis, a pair of templates, means for positioning said templates upon the table, each of said templates being adapted fittingly to receive the forepart and shank of a loose outsole and the upper portion of a loose heel with a flap portion of the outsole overlying the breast of the heel, said table being movable as an entirety lengthwise of said axis selectively to move one of the templates and accordingly the outsole and the heel positioned by said one template to a flap applying station opposite said block and to move another template to a loading and unloading station at one side or the other of the flap applying station, resilient means for constantly urging the table in one direction about said axis to a retracted position in which the heel receiving portion of the template at the flap applying station is spaced substantially from the block, manually operated means for moving the table against the action of said resilient means from its retracted position to a projected position in which the heel in the template at the flap applying station is forced lightly in nestled engagement with the flap portion of the outsole in this template and said flap portion is forced against the block, and power means operative in response to the tilting of the table to its projected position for forcing the breast of the heel under heavy pressure against the flap supported by said block.

13. In a machine for assembling a loos-e outsole and a loose Louis heel, a fixed frame, a resilient block adjustably secured to the frame, a table mounted on the frame for tilting movement about an axis, templates positioned upon the table, each of said templates being adapted to receive fittingly a forepart of the loose outsole and the upper portion of a loose heel with a flap portion of the outsole in opposed relation to the breast of the heel, said table being movable as an entirety lengthwise of said axis selectively to move one of the templates and accordingly the outsole and the heel mounted on it to a flap applying station opposite said block and to move another template to a work loading and unloading station adjacent to the flap applying station, a stop, resilient means for constantly urging the table about said axis to a retracted position which is determined by said stop and in which the flap portion of the outsole overlying the breast of the heel is spaced substantially from said block, means for manually moving said table against the action of said resilient means from its retracted position to its projected position to cause the breast of the heel to be forced against the flap portion of the outsole and said flap portion to be forced against the block, plungers operative respectively against the rear shank portion of the heel and the rear portion of the rim of the attaching face of the heel to force under heavy pressure the breast of the heel against the flap portion of the outsole supported by the block, and

power means operative in response to movement of the table to its projected position for operating the plungers.

14. In a machine for assembling a loose outsole and a loose heel, a main frame, a sleeve which has a bore and is journaled on said frame and which has an axis, a table comprising a shaft which is journaled in said sleeve and is slidable lengthwise of said bore, a resilient block mounted on the main frame, a pair of templates which are supported by and are positioned side-by-side on the table and each of which has a cavity for fittingly receiving a forepart and shank of an outsole and a rim portion of the attaching face of the heel with a flap portion of the outsole arranged opposite a breast of said heel, an actuator secured to the sleeve and comprising rigid and yieldable abutment portions adapted to engage different lengthwise portions of the table arranged at opposite sides of said sleeves, said table comprising abutments which are adapted to engage respectively opposite ends of the sleeve selectively to position One or the other of the templates at a flap applying station opposite said block while the other template is in a loading and unloading station at one side of the flap applying station, a spring for causing the actuator constantly to urge the table toward a retracted position in which the outsole arranged in the template at the flap applying station is spaced substantially from the block, manual means for tilting the table about the axis of the sleeve from its retracted position to a projected position in which the flap portion of the outsole is forced with light pressure against the block by the breast of the heel, one or more plungers mounted for movement in the main frame, and power means responsive to movement of the table to its projected position for causing said plungers to operate against the heel to move it toward the resilient block whereby to force with heavy pressure the breast of the heel against the flap portion of the outsole and said flap portion against said block whereby to secure by the use of adhesive the flap portion of the outsole to said breast.
